Rhenium is a silvery white element with a metallic luster. It has a high-density point exceeded only by platinum, iridium, and osmium, and its melting point is exceeded only by tungsten and carbon.
The usual commercial form of the element is powder, but it can be consolidated by pressing and resistance-sintering in a vacuum or hydrogen atmosphere.
Rhenium had good wear resistance and can withstand corrosion. Therefore, it’s commonly used as an electrical contact material. Rhenium wire is used in flash photography. It is used in the hydrogenation of fine chemicals and as an additive to tungsten and molybdenum-based alloys.
Preparation of Rhenium Powder Preparation of rhenium powder refers to the metallurgical process of producing metal rhenium powder from rhenium compounds. The rhenium compounds commonly used in the production of rhenium powder are ammonium perrhenate, potassium perrhenate, rhenium(VII) oxide, and rhenium pentachloride. The commonly used methods for the preparation of rhenium powder include hydrogen reduction, electrolysis, and […]

What Can Rhenium Be Used For? Rhenium is classified as a scarce refractory metal. It has the second-highest melting point of any of the metals and has a relatively high density. Rhenium is produced as a powder from molybdenite, which also contains rhenium sulfide. The rhenium powder is consolidated by pressing and resistance sintering in […]
What Is Rhenium Metal Powder Used to Make? Only tungsten and carbon have higher melting points. Rhenium has good wear resistance and it can withstand arc corrosion. It is soluble in nitric and sulphuric acids. Applications for the metal include its use as an alloying element with tungsten. The rhenium powder is a light-gray metal […]
